A hard disk drive embedded digital satellite receiver with scene change detector for video indexing

Abstract

We present a hard disk drive embedded digital satellite receiver with a scene change detector for video indexing. We implement a scene change detection algorithm in the compressed domain for low computing power systems. This receiver can store, retrieve and manage the broadcast data by implementing an interface between the conventional digital satellite receiver and digital storage media. In addition, this receiver gives users an ability to search the scene change position by implementing a scene change detection algorithm. The detected temporal video segments are stored in the HDD and retrieved when users want them. The user can obtain more information for efficient video retrieval, using this proposed system.
